The people of colonial Angel Grove (!) panic at the arrival of teens from the future. White and Green Rangers save the township from rat monsters; Green then stays in the past as White takes his friends home.

An alien crash-lands near Kyoto; trained by a local samurai, he becomes Katana, Earth's first alien samurai.

"Samurai" (Katana, 160 years)

"Messenger, part 1" (series date of 2025)

1880

Kimberly and villains visit Wild West Angel Grove from 1995; with Zordon's help, Kim's teammates' ancestors become "the first Earthlings to use the Power Coins." Also present is the "White Stranger" (Tommy's ancestor?).

In a magical dimension, Leanbow and four other wizards prevent Morticon from attacking the human world. Daggeron is attacked by his former ally Callindor, and both are sealed away. Bowen (son of Leanbow and Udonna) is left in the human world, where he will be raised under the name Nick.

In an "estimated future" described by Blue Senturion (right), the universe will be conquered by an evil alliance including Rita and Zedd, the Machine Empire, and Divatox (compare with 1998).

A message dated 2000 reveals the force capable of saving the universe (it may include Carlos and Ashley, below).

"The Millennium Message" (Blue Senturion, message)

"A Drive to Win" (Carlos and Ashley conspicuously targeted)

summer 1997 (cont'd)

Blue Senturion arrives from the future, warning of an evil alliance (left); it's unclear what changes result from his presence.

"The Millennium Message"

summer 1997 – early 1998

Four of the Turbo Rangers retire; T.J. and Cassie join Carlos and Ashley as replacements.

Adam will later run a dojo. Tanya may pursue a singing or radio career. Tommy will later meet Hayley while studying paleontology. Kat may attend the Royal Academy of Dance in London; will she and Tommy eventually marry?

General Havoc brings Metallasaurus and a space base; the Phantom Ranger gives the Rangers Rescuezords.

After being tested on Earth, Robot Rangers depart for Eltar (it's unknown whether they will be the Turbo team seen in the Legendary Battle).

Dark Specter's forces storm Eltar and capture Zordon. The Power Chamber is destroyed, and the teens chase Divatox in the Megashuttle. Justin remains behind.

On the planet Andresia, Orion finds a Morpher and Ranger Key in a quarry; over a week later, the Armada invades and wipes out most of the populace (all but Orion?). He learns to survive on his own and spends many months training, believing the Sixth Rangers from his visions want him to save other worlds.

"Silver Lining, part 2"

~2013 (est.) ("months" before "Silver Lining")

Orion downs an Armada ship; he will spend additional months repairing it before setting out in search of the Armada.

"Silver Lining, part 2"

2013–2014 (est.)

Vrak (son of Emperor Mavro) joins the Warstar aliens in attacking the Earth. Gosei recruits five teenagers as Mega Rangers.

Orion arrives on Earth, unlocking the sixth-Ranger keys (and a Q-Rex Zord apparently from the future).

The Rangers venture into the RPM dimension and retrieve the Turbo Falcon Zord from Corinth. Professor Cog is destroyed (again).

Following Vekar's death, Vrak returns with Robo Knight as his slave. Robo Knight gives his life force to Orion, and Vrak is destroyed.

Emperor Mavro launches a full-scale invasion of Earth but falls to the Rangers. Past Ranger teams (curiously including Turbo, Time Force, SPD, and RPM) help the Mega Rangers finish off the Armada's ground forces in a “Legendary Battle.”

Sam is the last child born to SPD pioneers; he will be living on the streets in 2025.

"Sam, part 2" (Sam, age estimated)

"Messenger, part 1" (series date of 2025)

2015 (est.)

Some time prior, Kendall has helped Keeper find Energem users Chase and Koda. The Dino Charge team is completed as Tyler, Shelby, and Riley join with Energems of their own.

A-Squad, Broodwing, Mora, and Gruumm are defeated and confined. Nova Ranger accompanies Sam back to the (revised?) future.

Jack retires; Sky and Bridge are promoted, and the rank of A-Squad is retired.

At some point, Doggie is promoted to supreme commander of SPD, with Sky replacing him as head of SPD Earth. Bridge becomes Red Ranger and will go back in time to help the Overdrive Rangers.

It's unknown from which point in time the SPD Rangers hailed to participate in the Legendary Battle. (Also note the Omega Ranger was seen in Orion's sixth-Ranger visions.)

2040 (without Omega in 2025)

Years after the fall of SPD Earth, Emperor Gruumm continues to rule the planet. Grown-up Sam ventures into the past as the Omega Ranger.

Weeks later, on July 11, the resistance broadcasts a distress signal on the 15th anniversary of SPD's defeat.

"Messenger, part 1"

2040 (with Omega in 2025)

The state of Earth in the wake of Gruumm's defeat is unrevealed (but see 2135). Do Sam and Nova return to this future? Did the Nova seen in 2025 hail from this future or the left panel? Did any of these changes to history affect the future of Time Force?

Does Sky still head SPD Earth? How long did Bridge serve as Red Ranger?

"Messenger" (Earth saved?)

"Once a Ranger" (Sky, Bridge)

~2045–2055 (est.) (unknown timeline)

In one possible timeline, Tommy and Kat have at least two grandchildren, one of whom is apparently a Ranger.

Still alive, Alex serves as the mysterious head of Time Force (was this always true or a result of changes to history?). Alex monitors the concurrently unfolding events of 2001 and eventually sends the Time Shadow to help.

As Frax prepares Dragontron in the past, Alex grows concerned with deviations from the history banks and travels back to intervene. He returns after healing Mr. Collins on his deathbed (the impact of this change is unknown).

Alex later blocks Circuit's remote access to the history banks as a time hole crisis looms in the past. Alex rescues his team with a Timeship (they died originally), but, learning of Wes's death in the past, the team goes back to save the day. They return to the future with Ransik in custody.

The future appears relatively unaffected regardless of whether Silver Hills was or wasn't destroyed in 2001 (and was this also the case whether or not Emperor Gruumm conquered the Earth?).
